Flowers were my first love, and the reason I got into this business,” says event designer David Stark. “When I started working with flowers to support my painting, I had no thought in the world that I would actually have this event planning and production company one day.”

Stark, 38, has parlayed his passion for posies – and his fine-arts background, including degrees from the Rhode Island School of Design and the School of Visual Arts – into a successful business, producing lavish events for the likes of Beyonce, Jon Stewart, MoMA and Coach.

All the glittering events he produces, however, get their start in a three-story building on Luquer Street in Carroll Gardens, Brooklyn, home base for Stark’s crew of 22 employees and home to Stark himself.

Long before he purchased the property, Stark resided there, as one of several struggling artists renting rooms. It was from his old second-floor apartment that he and former business partner Avi Adler launched their event-planning company 13 years ago. “If we had to put in another desk, out went the sofa,” Stark recalls. “Eventually, the business overran the loft.”

Now, David Stark – the man and the company – occupies all three floors, from a ground-level workshop to second-floor offices to the penthouse residence.

“When I first moved here,” says Stark of his top-floor apartment, “this was just an open roof with a ramshackle cottage and no deck. I totally redid the place.” Working with architects Jim Bartholemew and Robert Farrell, Stark created an airy retreat from the storms and stress that transpire below. “I wanted it to be comfortable,” he says. “My work is chaotic, so it’s important to me that my home is tranquil.”

Green therapy plays a key role in maintaining that sense of calm. “Every morning,” he says, “I get up two hours early to play in the deck garden. I love it. I hang out here every single day, even in the winter.”

Interspersed throughout the deck’s lush foliage is an eclectic assortment of furniture and objects, each with personal significance to Stark: a chair owned by his late grandmother, which Stark re-covered in cowhide; an old armoire from India; a bird’s nest brought back from Provence; even a life-sized plastic deer from a Target event he produced.

Beyond the wall of moveable glass panels, the apartment proper features more mementos from Stark’s past projects. “Things made for events often become things in my home,” he says. “They rotate in and rotate out.”

Currently, he’s showcasing a virtual forest fashioned for the Sundance Institute’s 25th anniversary gala last fall. (Stark is also doing the organization’s upcoming bash on Nov. 5.) “For Sundance, this tree’s leaves were made out of maps of Utah,” Stark says, “but for the apartment, I painted the whole thing white. And these flowers were created out of Sundance scripts.

“As with the events we do, I approach my house almost like a really big collage,” Stark says. “I add something, react to it, add something else, react to it.”

Recent additions include pottery decorated with colorful dots that Stark created in a class he’s been taking, in part as preparation for a possible future venture.

“After doing the third book [“Napkins with a Twist,” Artisan], I feel I’d like to make objects,” he says. “I’m particularly interested in making tableware; we just can’t find plates we like from the standard rental companies.”

The bedroom and bathroom are separated from the kitchen/living space by a central wall, open on both ends, that contains storage for everything from pantry supplies to a washer/dryer to a concealed TV and stereo.

“Downstairs is so much about stuff,” he says, “that in my home I want the ugly things like cords and wires to disappear.”

Still, Stark certainly isn’t going for the Spartan look. “When I started [decorating], I thought minimalism was going to be the way,” he says. “I thought, ‘I’m going to have a bed of dove feathers and that’s it.’ But the reality is that minimalism takes a tremendous amount of discipline. And I love stuff – collecting it, living with it. I embraced that fact a long time ago.”

David Stark’s 5 favorite things

* The local artisans and shops. “The welders across the street typically make window gates and screen doors,” Stark says, “but for us they make chandeliers, candelabras, structures for chuppahs.”

* His downstairs studio, which Stark calls “the most glorious flea market in the world.”

* The walk-in flower fridge, which not only serves as an on-site floral resource for an “apartment pick-me-up,” but also stores food and drink when Stark entertains.

* The covered deck. “It brings a little bit of the country to my urban street.”

* His team. “Living right above the office allows me to spend a lot of time daily with people I adore.”
